Mugabe, 89 and in power for 33 years, has another five-year term in office, according to the results.

Mugabe’s party won 158 of the 210 parliament seats, giving it a two-thirds majority in the legislature that enables it to make amendments to the new constitution and existing laws, according to the results announced by the state Election Commission. Tsvangirai’s party captured 50 seats and two went to independent candidates.

Tsvangirai earlier Saturday rejected the results as fraudulent and called for fresh elections. He urged a peaceful response to the alleged massive rigging by Mugabe’s ZANU-PF party.

Tsvangirai said his Movement for Democratic Change party has in its possession evidence of massive rigging by Mugabe’s ZANU-PF party in the just-ended polls and will challenge results from Wednesday’s voting.

“People of Zimbabwe must be given another chance to participate in a free, fair and credible election. They have been shortchanged by a predetermined election,” he said.

Tsvangirai told a news conference that the outcome of the polls has extended Mugabe’s rule which has plunged the nation into economic and political turmoil.

He said Mugabe’s victory in the polls has “dashed people’s hopes and aspirations.”

“There is no celebration, there is national mourning,” Tsvangirai said.

He said his party will not “participate in any government institutions” in protest but stopped short of saying it will boycott its reduced seats in the Harare parliament.

Mugabe’s loyalist army and police have set up security posts in Harare Saturday, apparently in case there are any protest demonstrations.

“We are rejecting the results because they are fraudulent,” Tsvangirai said. “We will go back to our people. Our people are the ones hurting. Our people are disciplined. We don’t want a violent resolution to this crisis.”

He said a complete audit is needed of the shambolic voters’ lists, which was only made available at the time of the election.

British Foreign Secretary William Hague expressed “deep concern” over the conduct of the election, saying the failure to share the voters’ roll with political parties was a “critical flaw.”

Hague said that and other irregularities “call into serious question the credibility of the election.”

“We note that some political parties have rejected the result on the basis of these irregularities,” he said, without saying whether Britain endorsed their move. “We will need to examine what has happened and consider further reports from regional and local observer missions. In the meantime, it is important that all allegations of electoral violations are thoroughly investigated.”
